Along with the cosmonauts first “space” generation of Drosophila melanogaster flies also returned to the Earth. It was the first generation received after Foton-M #4 flight. The flies were sent to the ISS onboard Progress M-25M cargo vehicle on October 29, 2014. The main purpose of this experiment was to study rucurring zero-g impact on multi-cellular highly organized living organism.

The results of these studies are of great importance for further deep space exploration.
